Web site Traineo is a weight loss and fitness tracker designed to keep you motivated to achieve your fitness goals.

Aside from the bevy of graphs and tables for tracking your exercise and diet habits, Traineo has a really interesting concept wherein you choose up to 4 motivators (friends, family - whomever) to receive weekly progress reports from Traineo. I sort of love this idea, since I'm big on the notion that announcing your goals is a terrific motivator. Finally, Traineo has its own community features for sharing encouragement within the Traineo community.

I'm not often wowed by fitness web sites, but on first blush, I'm really impressed with Traineo. That said, I'd love to hear what our health- and fitness-conscious readers think, so let's hear your thoughts in the comments or at tips at lifehacker.com. — Adam Pash
